CVE-2023-33613 1 Axtls Project 1 Axtls 2023-12-10 N/A 5.5 MEDIUM
axTLS v2.1.5 was discovered to contain a heap buffer overflow in the bi_import function in axtls-code/crypto/bigint.c. This vulnerability allows attackers to cause a Denial of Service (DoS) when parsing a private key.
CVE-2019-10013 1 Axtls Project 1 Axtls 2023-12-10 7.8 HIGH 7.5 HIGH
The asn1_signature function in asn1.c in Cameron Hamilton-Rich axTLS through 2.1.5 has a Buffer Overflow that allows remote attackers to cause a denial of service (memory and CPU consumption) via a crafted certificate in the TLS certificate handshake message, because the result of get_asn1_length() is not checked for a minimum or maximum size.
CVE-2019-9689 1 Axtls Project 1 Axtls 2023-12-10 5.0 MEDIUM 7.5 HIGH
process_certificate in tls1.c in Cameron Hamilton-Rich axTLS through 2.1.5 has a Buffer Overflow via a crafted TLS certificate handshake message with zero certificates.
CVE-2019-8981 1 Axtls Project 1 Axtls 2023-12-10 7.5 HIGH 9.8 CRITICAL
tls1.c in Cameron Hamilton-Rich axTLS before 2.1.5 has a Buffer Overflow via a crafted sequence of TLS packets because the need_bytes value is mismanaged.
CVE-2018-16150 1 Axtls Project 1 Axtls 2023-12-10 4.3 MEDIUM 5.9 MEDIUM
In sig_verify() in x509.c in axTLS version 2.1.3 and before, the PKCS#1 v1.5 signature verification does not reject excess data after the hash value. Consequently, a remote attacker can forge signatures when small public exponents are being used, which could lead to impersonation through fake X.509 certificates. This is a variant of CVE-2006-4340.
CVE-2018-16253 1 Axtls Project 1 Axtls 2023-12-10 4.3 MEDIUM 5.9 MEDIUM
In sig_verify() in x509.c in axTLS version 2.1.3 and before, the PKCS#1 v1.5 signature verification does not properly verify the ASN.1 metadata. Consequently, a remote attacker can forge signatures when small public exponents are being used, which could lead to impersonation through fake X.509 certificates. This is an even more permissive variant of CVE-2006-4790 and CVE-2014-1568.
CVE-2018-16149 1 Axtls Project 1 Axtls 2023-12-10 4.3 MEDIUM 5.9 MEDIUM
In sig_verify() in x509.c in axTLS version 2.1.3 and before, the PKCS#1 v1.5 signature verification blindly trusts the declared lengths in the ASN.1 structure. Consequently, when small public exponents are being used, a remote attacker can generate purposefully crafted signatures (and put them on X.509 certificates) to induce illegal memory access and crash the verifier.
CVE-2017-1000416 1 Axtls Project 1 Axtls 2023-12-10 5.0 MEDIUM 5.3 MEDIUM
axTLS version 1.5.3 has a coding error in the ASN.1 parser resulting in the year (19)50 of UTCTime being misinterpreted as 2050.
